IFRS 8 Operating Segments is the standard now in force that specifies the reporting of segment information by groups. The standard is a convergence one and its wording is exactly that of the US standard SFAS 131, apart from editorial changes to conform the vocabulary to IFRS terms instead of US GAAP ones. The standard applies only to listed groups and specifies what constitutes a reportable segment and what information should be provided. The key issues are that the information should be the same as that provided to the ‘chief operating decision-maker’ in a group. Consequently it may not be based on IFRS measurements, although it must be reconciled to the numbers in the financial statements.

It has a practical advantage that, as compared with the previous standard, it does not require the group to prepare special numbers that are used only for public reporting.
